/***
 * 格式化HTML的代码用途：样式HTML（HTML源代码）；

 选项包括：
     缩进大小（默认4）-缩进大小，
     缩进字符（默认空格）-要缩进的字符，
     max_char（默认值70）-每行的最大字符数，
     大括号样式（默认“折叠”）-“折叠”“展开”“结束展开”
     将大括号放在与控制语句（默认）相同的行上，或者将大括号放在自己的行上（allman/ansi样式），或者只将结束大括号放在自己的行上。
     未格式化（默认值['a']）-不应重新格式化的标记列表
     缩进脚本（默认正常）-“保持”“分开”“正常”
 例如

 样式HTML（HTML源代码{

“缩进大小”：2，

'缩进字符'：''，

“最大字符”：78，

'大括号样式'：'展开'，

“未格式化”：[“A”、“Sub”、“Sup”、“B”、“I”、“U”]
